About
The Emergency Distress Terminal is a robust device designed for critical situations, offering dual communication channels through the Tianqi satellite system and AIS maritime communication. It integrates Beidou and GPS dual-mode positioning for accurate location data. Key features include a dual-backup distress alarm system (Tianqi + AIS), one-button activation for sending Tianqi satellite distress messages, and automatic alarming upon water immersion (triggered by cap removal). The device is engineered for low power consumption, extended battery life, and portability. It can transmit distress information to up to three emergency contacts, significantly improving the reliability of rescue operations. Its compact size and lightweight design make it easy to carry, while its IP67 protection rating ensures durability in harsh environments. The terminal supports sending Tianqi messages containing time and location information, and AIS standard messages with similar data. It operates on UHF for Tianqi communication and specific frequencies for AIS, with high positioning accuracy and sensitivity.
